Toilet Installation &
Waste Piping Installation
Installing the "1
Pint" Low Flush Toilet
The center of the 3" waste
pipe needs to be more than 10¼"(26 cm) from the rear wall
(if a Sealand is being installed) and 8" (20.5 cm) from the
The Sealand is mounted on a 4
bolt floor flange (not supplied). A 2 bolt floor flange can be
converted to a 4 bolt by drilling two extra holes in the flange to
line up with the toilet's mounting bolts.
A Universal Mounting Kit
(available from Sun-Mar) can be used to adapt an existing 2 bolt
floor flange to a 4 bolt installation. Complete toilet
installation instructions are included with each toilet.
Installing the Waste Inlet
Please see diagrams below for
When installing the waste piping
from the toilet to the composting unit, the following
considerations should be kept in mind:
i) The piping should be either 45
degrees or more to the vertical, and/or at a 2-3 degree angle (¼"
to " drop per foot) so that the waste travels with the
liquid. Piping should not be installed at between 4 and 45o, as
the water will run ahead of the waste.
ii) Piping should not slope
upwards at any point.
iii) Connections should be snug
so that waste is not encouraged to "hang up" where pipe
iv) If the horizontal travel is
longer than 15 feet, a clear-out port (a Y fitting with screw on
end cap) should be installed near to the toilet to provide easy
access should it ever be required. Sun-Mar does not recommend an
installation over 20 feet, as clogging will occur.
v) Use a soft sealant such as
silicon for the connection of the waste piping to the composting
unit so that the composting unit can be moved for servicing or
other reasons should this ever be required.
vi) Insulate piping if unit is to
be used during the winter. For heavy winter use, the composting
unit will need to be kept warm by enclosing it, insulating the
enclosure, and providing some heat source. The enclosure must not
be airtight since the unit must be able to draw air in.
If you need to put the composter
outside or underneath the cottage, and it is an electric model,
ensure that the electricals at the base are protected from ground
water, heavy weather, and/or snow melt. Many customers construct
an enclosure for this purpose. Also, ensure that it can drain
properly into your overflow facility. If the unit is installed
below grade, a pump may be required to pump the overflow liquid
back to the overflow facility.
